Torture/ rommay concern: I

Be it known that JOHN M. FREEMAN, a citizen of the United States, residing at Hickorv. in the county of Catawba and State ofllorth ,Carolina, have invented new and iiseful" Improvements in Filling-Grate Clearing li'ieans for Looms, of whichthe following is a specification. i

r The object of my said invention is the provision of suillcient means forkeeping the filling grate'ofa loom perfectly clean in orderto enable the fork'to be instantly effective when there is no filling between it and the grate, this in order to avert thin placesinclotli as when the filling grate 1s choked ivith'lintor waste or threads so that the filling motion will work as if all of the organized mechanism was in proper working condition. Manifestly my improvement characterized as indicated w1ll save the labor necessary to the manual cleaning of a filling grate and will also obviate the necessity of stopping a loom for such cleaning.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a vertical section of so much of a loom as is necessary to illustrate the application of my improvement.

Figure 2 is a detail perspective showing the improvement and the loom parts adJacent thereto.

Figure 3 is a section through the attachment.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The loom illustrated includes the usual frame arch 1, a brake wheel 2, an oscillatory lay 8, and a filling motion including the usual means for driving the motion, a filling grate 4, and a filling fork 5 as well as the usual loop or hook 6 behind the fork.

When filling is absent from the path of the fork when the fork approaches the grate, the fork will dwell, and the loop or hook 6 will engage the filling motion and cause it to operate for the changing of the filling or the stopping of the loom. My improvement is designed to avert choking of the filling grate and to maintain said grate at all times in a clean condition so that the fork .\'ill, act promptly when thereis no filling between the, fork and the grate." The saidimprovement among other elements includes a rotarybrushfmade' up of a head 3? id. tufts e er longand soft and flexible bristles. "The 'sa'id head 7 of the brush is appropriately fixed on a spindle 9, and the brush is so arranged relatively'to the filling grate a as. toassurothe filling grate movinginto "contact with the bristles of the bru slrf'atthe back center position of the lay 3yjincident to thelback and. forth movements of the lay. The spindle 9 is arranged to turn ina long tubular bearing 10, and the said spindle 9may be driven or located fromany desired working part 'of the loom without affecting my claimed invention. For example I may provide the spindle 9 at the opposite end of the bearing 10, with reference to the brush, with a pulley 11 and may connect said pulley by a belt, Figure 1, with a pulley on the shaft of wheel 2, so that in the illustrated embodiment of my invention the rotary brush derives motion from the said shaft of wheel 2. The tubular bearing 10 isdisposed in a sleeve 12 on a bracket 13, and a set screw 14 is employed in the said sleeve 12 to adjustably fix the tubular bearing 10 in the sleeve so that the brush can be accurately positioned relatively to the filling grate 4:.

The bracket 13 in the presentand preferred embodiment of my invention is bolted or otherwise fixed, preferably in adjustable manner, to the frame arch of the loom.

In the practical and successful use of my invention which has been reduced to actual practice, the rotary brush has demonstrated with its efficiency in the cleaning of a filling grate, and experience has also demonstrated that the brush will serve the purpose stated in the dampest places in a weave room or not desire, however, to be understood ,as confining myself to the said' s'pecific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall Within the scope of my invention as defined in my appended claims.

Having described myinvention, What I claim and desire to secure by Letters-Patent, is

1. The combination in a loom filling-grate cleaning device, of a rotary brush, means to rotate the brushyand a filling motion including a filling grate arranged to contact with the brush on movement of the lay of the loom.

2. The combination in a loom filling-grate cleaning device, of a rotary brush, means to rotate the brush, and a fillingrmotion in? cluding a filling grate arranged to contact with the brush on movement of the lay of the loom; the said brush including a body and tufts of radial bristles on the body.

3. The combination in a loom filling-grate cleaning device, of a rotary brush, means to with the brush on movement of the lay of the loom ;'-and"said brush comprising a body and tufts of radial bristles carried thereby, and the brush being fixed on a rotary spindle, and thespi-ndle being journaled in a tubular "bearing .adjustably fixed in, 'a

bracket on the loom frame.

rotate t e brush, ,and a? fining motion ineluding a' filling grate arranged to contact 4;. A loom filling-grate cleaning attachment comprising a bracket, a spindle carried thereby, a brush fixed on the said spindle, and a drive element for the spindle fixed thereto.

5. The combination in a loom filling-grate cleaning attachment of a bracket with a sleeve, a tubular bearing disposed and adjustable in the sleeve of the bracket, means to adjustably fix said tubular bearing in said sleeve, a spindle journaled in the sleeve, a brush fixedto the spindle at one end of the sleeve, and a rotary driving element fixed to the spindle at the opposite encl'of the sleeve.
